目的:探讨血清降钙素原(PCT)和C-反应蛋白(CRP)诊断细菌感染性疾病的临床应用价值。方法:选择100例细菌感染性疾病患者(观察组)与100例非细菌感染性疾病患者(对照组),比较两组PCT、CRP水平。结果:观察组PCT水平、检测阳性率明显高于对照组(P<0.05);观察组CRP水平、检测阳性率明显高于对照组;PCT诊断细菌感染性疾病灵敏度、特异度等指标均明显高于CRP检测结果(P<0.05)。结论:PCT诊断细菌感染性疾病敏感度高于CRP,监测PCT水平对于临床中诊断、治疗细菌感染性疾病具有重要的意义。
Objective: To investigate the clinical value of serum procalcitonin (PCT) and C-reactive protein (CRP) in the diagnosis of bacterial infectious diseases. Methods: One hundred patients with bacterial infectious disease (observation group) and 100 patients with non-bacterial infectious disease (control group) were selected. The PCT and CRP levels were compared between the two groups. Results: The PCT level in the observation group was significantly higher than that in the control group (P <0.05). The CRP level and the positive rate in the observation group were significantly higher than those in the control group. The sensitivity, specificity and other indexes of bacterial infection in PCT were significantly higher The CRP test results (P <0.05). Conclusions: PCT is more sensitive to diagnose bacterial infectious diseases than CRP. To monitor PCT levels is of great significance in diagnosis and treatment of bacterial infectious diseases in clinic.
